Call blocking
Activates or deactivates the signalling of calls on your terminal for all call keys /
call numbers (INTERNAL/ EXTERNAL / MULTIPLE keys). An internal caller obtains
the busy signal or a special dialling tone indicating that call blocking has been
activated. An external caller obtains either the busy signal or is switched
through to the operator.
Block call key
This function allows you to activate or deactivate call blocking for an individual
call key / call number (also a MULTIPLE key on other devices). Select the key for
which you want to set call blocking. See the previous section for the signalling
when call blocking is activated.
Call waiting on/off
While you are making a call, i.e. while your phone is busy, authorised internal
subscribers can activate call waiting and signal their presence to you. To pre-
vent them from doing so, you can deactivate the call waiting option.
Block intrusion
If this feature is activated, an authorised subscriber will be unable to intrude on
an existing call. If this function is not activated, authorised subscribers can
intrude on calls and send you a message.
Restrict dial
You can switch the access rights to your phone, for instance to prevent unau-
thorised call charges (Restrict dial). Activating this function switches your
phone over to “restricted access” (allowing only incoming external and outgo-
ing internal calls). To do so, you need to enter your device PIN (default setting:
“0000”). Any emergency numbers that should be diallable despite the restricted
access will be set up by the system administrator.
Change PIN
This PIN should not be confused with the PIN used for locking the device
(phone lock, see also page 82). The PIN specified here is required for system set-
tings (such as the “Restrict dial” feature). Enter your old device PIN (default set-
ting: “0000”), then enter the new PIN twice. If you no longer have your device
PIN, the system administrator can set up a new PIN for you.
Cancel features
Cancels all the active features that affect your availability (call blocking, call
diversion, call waiting on/off). These are the features you can find in the “Active
features” list in the Info menu.
